Question

1. what is the contour interval of the topographic map below?

Explanation:

Step1: Identify contour - labeled values

We see contour lines labeled 400 and 800.

Step2: Count the number of contour - intervals between the labeled lines

There are 4 contour - intervals between the 400 and 800 contour lines.

Step3: Calculate the contour interval

The difference in elevation between 800 and 400 is \(800 - 400=400\). Divide this difference by the number of contour - intervals. So, the contour interval \(=\frac{800 - 400}{4}=100\).

Answer:

100
